thats when u can borrow one of his arsenal 
anyway, i didnt have a macro lens when i had fun 

Never! Hahahaha... probably not so soon la. I am trying to refrain myself from letting the poison spread too far. My monthly expenditure is teruk, the most typical cannot-save-money kind of guy. Possibly end of next year get one kua, depends on what's released.
Well, I had the choice to get the 18-55 + 55-250 when I bought the 40D body only. At the same time, I considered the Sigma 18-200mm OS. Despite the fact that 18-55 and 55-250 has 4 stops IS and it's Canon, I went ahead with Sigma 18-200mm OS for the simplest reasons.

1. Dont want carry 2 lens
2. Dont want change lens
3. Dont want to miss a moment
4. Dont want lens to take up space in my bag
5. Price is same <-- this may not be applicable since this lens is Canon and it's f/3.5 - f/5.6 while Sigma is f/3.5 to f/6.3 meaning at 200mm Sigma is f/6.3 and Canon is f/5.6. So I am assuming this lens going to be EXPENSIVE.

Second hand 70-200mm f4 L dont give you wide angle at 18mm. At the same time, save up a lot and straight go for 70-200mm f/2.8 L (with / without IS).

currently i'm shooting some events and occasionally some macro shots..

I already have a EF 50mm f1.8 and EFS 17-85mm f4-5.6 IS. Unfortunately the 17-85mm has been plagued with problems that it has been in and out of the ICU for more than 2 months already..

both lenses are 2nd hand, 50mm from a friend, and the 17-85 from YL camera shop. i think the 3 months warranty expired already but i never got to use that lens for 3 months. so now im considering to get another one to replace this one

see how la, actually, second hand thingy. if u get from trusted person, i dun think why not. plus, with second hand u can save a lot of $, and you can always consider the warranty etc before making a purchase

second hand 40D body onli, RM2999 used onli 1 month, like new, shutter less than 5k, will you consider?
